DRIVING DEVICE FOR LOOM PATTERN MECHANSM.

Application iled December This invention relates to driving devices lor pattern mechanism and it is the princi-v .Dal object ofy the invebntion to provide a` driving: sha'tthavingr operative connection with a multiple of devices and movable about a' tired center away 'from said devices to facilitate adjustment and assembly.

lt is` a more particular object of my invention tov4 mount tli'e' u pri.a'ht shaift ot the well-known Knowles head1 in such away as to permit the same to be'swungin a' vertical plane away trom the taire-up, selvag'eV and head drivingu devices without twistingl or bendingl said shaft it' is a turther object ol' my invention to provide an improved c lrivingr' connection be tween the upright pattern mechanism driving shaft antL the bottom shalt ot a loom.

lilith theseA and other objects in view vwhich will appear as the descriptionpro (reeds1 my invention residesin the combination' and arrangement oit" parts hereinafter described andl set 'forth in the claims.l

In* the' accompanying drawings, wherein l have shown' one 'form oi my inventiom Fig'. 1 is a side elevation of the rear portion ot a loom having my invention applied thereto, the front of the loom being` at the lett ot the structure shown,

Fig. 2 is a vertical section taken on linev f2-#2 of Fig, 1, and y Fig. 3 is a vertical section talre'n on line ot Fig. 2Q'

Referring to thev drawings it will'beseenv that l have provided a loom trame 10 in the lower portion of which is mounted for rotation a shaft 11 drivenv in any approved manner by mechanism'conveniently located on the opposite sideo'f the loom. Upstanding from thel :trameA 10 is an arch 12 having i ant arm 13' extending' rearwardly therefrom and' supportingfupper and lower bevel gears 'lefand 15, respectively,'said bevel gears cooperating with the cylinders of the' well lmownlnowles head as shown in Patent No. 134,992 issued' Jan. 22; 1873, to' L; J". Knowles.

A, stand 16 is4 secured to the trame 10 and has" ente ndi-ngy there-'troia ay studi 1f? onA which isy rotatably mounted a selvagge motion bevel gear 18'.- Atalrelup'shaft 19 similar to that illustratedin patent to l-yon No;'8'10', 6.80 is rotatably.mounted inc bearing 2Q and car? eo, i924,

meshes with a second gear 22 fastened to shalt 23, said sha-ft beingl received by bearing 24;' formed on a plate 25 secured to the loom frame. The rear end ot shaft 2,3 has secured thereto a bevel `Qjear 26 by means et which the same may be rotated to cause rotation of shatt- 19.

My invention relates more particularly to the upright shaft 8O by means' ot' which' the motions heretofore described areactuated. yThe upper end oli sald'shat't' hassecured thereto upper and lower bevel gears' 31e 22 t'v l b "l t h'h' o L.no L iespec 1vey, y means or w 1c the head motion bevel gears 14 and 15, respectively, are actuated. Extending between the gears 31 and 32 is a bearing Silone por-- tion 34 ol' which is` secured to the 'toot 13, and the other portion or' which is'formed as a cap 35 and secured to the portione; At a point intermediate the height thereof thev shaft 30 is provided with a second' bearing' 36 formed in part by al portion 37 which is formed integral withthe plate 1 6 and in part by a cap 38 removable `:trom the portion 37 and lying on the samer side of the shalt cap 35.

A bevel gear 39 is'secured to theshatt SO in proper'position for engagement with gear 18. Below the gear 39 isa sleevee() mountH ed for sliding motion onshatt 30 andhav ing upper and lower bevel gears il and 42, respectively, one ot which will bein mesh with the bevel gear 26. The vertical position of the sleeve 1 .is determined-by a'lever 113 pivoted as at 114 totheplate 25, said lever beinrqcontrolled as to position by means off a bell crank lever 415 pivoted to thestand 16 and receiving` motion from the reversing mechanism (not shown) ot'thehead.V

rllhe bottom of the uprightshaft is pro-w vided with a clutch indicated generally at 116 by means ot which said shaft receives motion Jfrom the'bottom shaft.' The clutch comprises' a sleeve 47' iixed to the upright shalt, a sleeve 4:8 sliding` thereon and having 'extending therefrom a pin L19, and a bevel gear which-receives' thelower end ol' the pin 119. The sleeve 18 is positioned b /j means o f a lever 51- controlledthrough arm 52 which may be raisedorlowered willby the operator when it isde'sired to turn the'head` by hand;

Thel bevel gearbO" meshes with" a corre# spending bevel"- gear 53"'sliowIr-rrfthepresent 'instance as mounted on the hub 5i of a plate 55 keyed to the bottom shaft at 56.

The angular position of the gear 53 may be varied with respect to the plate 55 by means of bolts 57 which pass through slots 5S `formed in the plate The bottom of shaft 30 is received in an upwardly extending bearing 5S) formed in an angularly adjustable support 60. Said support is provided with a flange 6l, having slots 62 therein through which extend bolts 63 which secure the flange 6l to a bearing Gil fixed to the loom frame l0. rEhe flange "G1 is held tightly to the bearing 64 by the bolts 63 but can be moved angularly with respect thereto when the bolts are loose.

vWhen the head is improperly timed it is necessary to correct the timing by adjl ting the angular position of the snaft 30 with respect to the bottom shaft ll, Under such conditions the cap bearings and "8 can be moved, the bolts 63 loosened and the shaft moved rearwardly in a vertical planc about the bottom shaft as a center to the position indicated in dotted lines in l?" gage the gears as described. After the gears have been given their proper adjustment the shaft may again he lowered and returned to upright position as shown in Fig. l, the caps and 3S replaced and the bolts 63 tightened.

F rom the foregoing it will be seen that l have provided a very simple means for mounting` the driving shaft of the well lrnown Knowles head in such a way as to permit the same to be swung rearwardlj7 to allow adjustment thereof with respect to the bottom shaft. Also, it will be seen that I have provided for the adjustment of bevel gear 53 with respect to the bottom shaft,
